8.14-Mile Stretch Between Sageville and Boy Scout Road Will Be Shut Down All Season; Marked Detour Via U.S. 20 and U.S. 52 in Place

DURANGO, Iowa — March 21, 2026 — Motorists who regularly travel Iowa Highway 3 west of Sageville should prepare for a major disruption beginning next week. The Iowa Department of Transportation (Iowa DOT) has confirmed that the entire 8.14-mile segment of IA-3 between Boy Scout Road and Sageville will close to all traffic in both directions starting Monday, March 23, 2026, at 7:00 a.m., weather permitting.

The closure is part of a full roadway reconstruction project designed to rebuild the pavement, shoulders, and drainage structures along this rural corridor. While the work will improve long-term safety and ride quality for thousands of drivers, it will require a complete shutdown of the highway for the duration of the construction season.

Closure Details and Scope

•  Road affected: Iowa Highway 3 (IA-3)

•  Length: 8.14 miles

•  Direction: Both eastbound and westbound lanes closed

•  Type of work: Full reconstruction (pavement removal and replacement)

•  Start date: Monday, March 23, 2026, 7:00 a.m.

•  Anticipated completion: Tuesday, December 1, 2026

Access for local residents and emergency vehicles will be maintained throughout the project via temporary crossings and signed local routes. However, through traffic will be prohibited for the full length of the work zone.

Official Detour Route

When the roadway closes, drivers must follow the posted detour:

1.  Proceed west on U.S. 20 to Dyersville.

2.  Turn north on U.S. 52 and rejoin Iowa Highway 3.

This detour adds distance and time compared to the direct IA-3 route, particularly for commuters traveling between Dubuque County communities and points west. During peak travel periods, motorists should expect additional congestion on U.S. 20 and U.S. 52, especially near Dyersville. Iowa DOT officials note that the detour has been designed to minimize impacts on major freight corridors, but drivers hauling oversized loads or using commercial vehicles are encouraged to plan routes in advance.

Why the Project Is Needed

This section of Iowa 3 has reached the end of its service life. Reconstruction will address deteriorating pavement, improve drainage to prevent future flooding issues common in the area, and bring the roadway up to current design standards. The work is typical of Iowa DOT’s annual pavement preservation program, which aims to extend the life of state highways and reduce long-term maintenance costs for taxpayers.

Safety Reminders and Enforcement

Iowa DOT is urging all drivers to treat the detour and surrounding work zones with extra caution:

•  Obey all posted speed limits and signs.

•  Traffic fines for moving violations in work zones are at least double the normal amount.

•  Maintain a safe following distance and stay alert for changing conditions, workers, and equipment.

•  Always wear seat belts.

Construction will continue through spring, summer, and fall, meaning conditions could vary widely depending on weather. Heavy equipment and flaggers may be present even on the detour routes during certain phases.

Broader Context and Considerations

This closure is one of several major reconstruction projects scheduled across northeast Iowa in 2026. While it will inconvenience travelers for several months, the finished roadway is expected to offer smoother, safer travel for years to come. Residents and businesses along the route are reminded that local access remains open, and emergency services have been coordinated with detour plans.

Commuters, delivery drivers, and tourists planning trips through the area in the coming months are strongly advised to build extra time into their schedules, check 511 before leaving, and consider alternative north-south routes if possible.

The Iowa DOT will provide periodic updates as construction milestones are reached. Motorists are encouraged to share this information with friends, family, and colleagues who travel Iowa 3 regularly.

Drive safely, slow down, and stay informed — Iowa’s roads are under construction for your future safety.
